Thanks for trying to help!
I only installed Ely's Silent Voice because one of the city expansion mods recommended it, and I didn't see any reason not to. Until the crashes started, that is. No, it has nothing to do with me changing dialogue around and copying over voice files. The reason I thought it had to do with security is that Windows 10 has many fancy new shiny hard [censored] rules that would just kill an application for no good reason (because it could be "malicious"). So I did have to fudge them a bit, because of this:
- Windows 10 prevents properly installed Oblivion from running batch files with BAT command from the console (security risk - could introduce Dark Brotherhood assassins, or worse - Morag Tong).
- Windows 10 prevents running Construction Set Extended with OBSE because it is capable of changing other programs (err... yeah? It makes mods!!). So it must run with administrator privileges.
- This does not extend to Oblivion itself, although the same OBSE DLLs are used. However, the latest OBSE versions (xOBSE) all recommend to run Oblivion with administrator privileges, presumably to avoid crashes.
- I cannot run Oblivion with administrator privileges because that kills my Xbox360 controller which Windows 10 refuses to run with administrator privileges.
- None of this nonsense existed in Windows 7!! But I haven't got it, I've got 10.
Anyway, let this notice stand in case someone else has similar issues, then they can read it and feel less alone.
I'll post something if I find a solution.
